What is the difference between a triangle and a pennant?

by Arthur Hill

Triangles and pennants look the same, but their timeframes and expectations are different. Pennants are short-term patterns that form after a steep advance or sharp decline. Pennants typically extend 1-3 weeks, after which a continuation of the prior move is expected. Anything longer is probably a triangle.

The Daily Routine

by Arthur Hill

Q: What is your daily analysis routine? A: My daily analysis routine involves a top-down approach. First, I check the intermarket charts to see what’s happening with the S&P 500 (SPY), bonds (TLT), gold (GLD), oil (USO) and the Dollar (UUP).

Sharpcharts subscribers can view a market summary page based on your favorites lists by selecting “summary” for the format (see green box below). The image Read More
